6 Volt

BatteryMart.com offers a lot of different 6 volt sealed lead acid batteries. Our batteries range in capacity as low as 500 mAh to 200, fitting thousands of applications. Most SLA batteries can be matched by their dimensions and voltage. Our sealed lead acid batteries are covered by our 1 year warranty.

6 volt SLA batteries are extremely popular in backup power supplies, like UPS backup units, and home alarm systems. UPS devices generally use F2 terminals (1/4") and home alarm systems use F1 (3/16").

Frequently Asked Questions about 6V SLA Batteries

What charger should I use for my SLA battery?
Some applications will charge the SLA battery automatically, like alarm or backup systems. You shouldn't need to take the battery out and put it on a charger.

If you do need a charger for your application, generally you will want a charger that is ~10% of the capacity rating of the battery (at a 20hr rate).

For example, if you wanted to charge a 6 volt, 5 Ah battery, you would select a 6 volt charger with about 500 milliamp charging output (5 x 0.10 = 0.5).

What SLA battery should I buy for my application?
We recommend starting with the voltage and dimensions. Most SLA batteries can be matched with that information. Then, you should check the terminal size and type. This is important if the battery uses spade (sometimes called blade) terminals as these come in two sizes: F1 and F2. There are adapters you can purchase at BatteryMart.com if needed.

The capacity will sometimes differ between manufacturers, but normally not be a great deal. Differences here may affect the runtime of the battery before it needs recharged. Larger capacity batteries will be able to run longer.
